The spat was sparked by Kobach’s proposal to throw out after 90 days names of more than 34,000 potential voters who registered in the state, but didn’t provide proof-of-citizenship documents like a birth certificate or naturalization papers.

Clinton’s campaign late Monday posted a comment on Twitter calling the plan a “targeted attack on voting rights,” including a link to a story from The Associated Press about it.

Koback retorted the next day on Facebook that it is not a purge as “left-wing knuckleheads” claim because those people just have to fill out another voter registration form again. He said Clinton is “getting her pantsuit in a twist over nothing.”
